+#Use`<H1>`tag only once
+
+* Every page should include a single `<h1>` tag and follow **descendance** for other header tags as well. The `<h1>` tag should contain up to **150 characters** of text that accurately summarises and describes the contents of the page.
+
+* If the page contains a significant amount of text, it should be organised with `<h2>` through `<h6>` subheadings that summarise and categorise the text that they precede.
+
+* **Search engines** rely on correctly used headings to determine the organisation and contents of a site.
+
+####Example
+
+```html
+<h1> Use H1 tag only once </h1>
+```
